Teoscar Hernández has taken a ton of deserved flack for his defense this season. He can't make routine plays and his arm is lacking, but the Dodgers insist on putting him in right field. Dave Roberts has gone as far as to call him out in front of the media.
He might not have invited so much criticism this season if his bat had performed to expectations this season (after he put up a -9 OAA at the outfield corners last year, but he was heralded as a Dodgers hero because of his offensive season), but it hasn't.
